There is a patch that allows you to select whether you'd like the standard Google Analytics URL (www.google-analytics.net/ga.js) or the Double Click URL (stats.g.doubleclick.net/dc.js). That's it.
I added a flag in the Admin screen so one can make the change there. The default remains the same.
The reason behind using the Double Click is to enable tracking of AdWord along Google Analytics and as a result get better advertising in front of our customers.
